(Cl. 23S- 30) This invention relates to a novel means for on the three indicating drums 1, 2 and 3 or on increasingthe capacity of a taximeter from the two groups of printing wheels would be $9.95 to $19.95 without making the machine $9.95. It is sometimes found that the fare runs larger, which would be necessitated if another to more than that amount. Additional printing 5 drum were added.

in the above mentioned patent. In operation the parts are held in the position The gears 4, 5 and 6 drive gears 18, 19 and shown in' Fig. 2 when the iiag is in for hire 20 on a shaft 109, which gears are secured to position, the parts being so held by the cam 24 printing wheels 21, 22 and 23 having type thereengaging the lever 25 so that the arm 36 holds on to print on a record as is fully set forth in the forward end of the yoke 35 in a raised 105 the above mentioned patent. All of the strucposition. The printing type carried by the exture thus far indicated is shown in the said pattension 47 is held below the printing position ent. and the printing type 43 is held above the print- It is obvious that with such a construction ing position while the indicating plate 40 is held the maximum amount that could be registered in a raised position so that it can not be read. 110

When the iiag is thrown to a tariil position the cam 24 is rotated away from the lever 25 but the lever is not `free to move for the reason that the ear 28 of the i 27 engages the lever 29. It is true that ng would tend to lower the link 37 but to do this it would be necessary for the lever 25 to rotate in countenclockwise direction, which cannot do. When the $1.00 printing wheel i7 is rotated 1ceyond the point Where the numeral 9 would be in printing position, the cam Se engages the nose 32 of the lever 29, partially rotating the lever in a clockwise direction against the tension oi the spring 3l so that the i end oi the lever 29 is depressed beneath the ear 28 thereby permitting the lever 25 to rotate. The spring all immediately pulls the link 37 downwardly and moves the printing type on the extension 47 into printing position and simultaneously moves the printing character 43 into printing position as well as the plate 40' into a position where it can be read. The parts would remain in this position until the meter was reset. The fare printing wheels and indicating wheels could continue their rotation beyond the $10.00 designation without in any wise interierring with the position of the indicating and printing characters 1.

When the machine was reset the various type and indicating wheels would reset in the conventional manner and the cam 24 would engage the lever 25 rotating it clockwise so that the ear 28 would engage the lever 29 and the arm 36 would elevate the link 37, moving the printing characters and the indicating characters out of printing and indicating positions.

It is readily perceived lthat instead of raising the link 37 it conid be lowered and the same results would be obtained. Furthermore, the 1ever 25 might be eliminated altogether by coupling the yoke 35 with the arm 29. Other changes might be made without departing rom the spirit of this invention. l, therefore, desire to claim the invention broadly in whatever form it may be embodied which may fairly fall within the scope or the present invention.

I do not desire to limit my invention to a taximeter as it can be used to advantage in other machines, such as cash registers, fare registers and the like.
